Quest Oculus^{(Oculus Quest)} ( labadaba nooca asalka ah iyo midka labaad^{(second model)} ) waxay leeyihiin taariikh xiiso leh oo astaamo lagu daray waqti dheer ka dib markii qalabku ka baxo duurka. Kuwa ugu caansan waa Oculus Link , kaas oo si wax ku ool ah u beddelaya Quest -ka ^(Quest)Oculus Rift . Habkani waxa uu ahaa mid aad loogu guulaystay oo Oculus waxa uu go'aansaday in uu joojiyo dhamaan sameecadahooda laakiin Quest . 

Dabagalka gacantu^(Hand) ma samayn wax la taaban karo oo Oculus Link sameeyay, laakiin wali waa muuqaal la yaab leh oo leh karti badan. Gacan ku-raadinta uma baahnid kontaroolayaal gabi ahaanba. Gacmahaaga ayaa digitized galiyay aduunka VR! 

Haddii aad leedahay Quest ama aad ka fekereyso inaad mid iibsato, waxaa habboon in la ogaado sida gacan ku raadinta u shaqeyso iyo waxa ay ku keeni karto khibradda VR.

Sidee Baadhitaanku ula socdaa Adduunka

Oculus Quest waxa ay isticmaashaa hab cusub oo ku wajahan dabagalka dhaqdhaqaaqa kaas oo inta badan lagu tilmaamo raadraaca “gudaha-ka-baxa”, kaas oo aad uga duwan sidii raadraaca mooshinku u shaqayn jiray waagii hore  .

Markii madax-madaxeedyada jiilka xiga ee ugu horreeyay la sii daayay bartamihii 2010-meeyadii, waxay isticmaaleen hal ama ka badan kamaradaha raadraaca dibadda. Nalalka raadraaca dhaqdhaqaaqa gaarka ah ee madaxa dhegaha ayaa u sheegay kamarada sida saxda ah meesha uu taleefoonka dhegaha ku xidhan yahay. Xisaab xariif ah, xogtaas waxaa loo rogi karaa raadraaca dhaqdhaqaaqa saxda ah ee booska 3D. Tani waa sida madax-madaxeedyada VR-da ee qaaliga ah ay bixiyaan "lix darajo oo xorriyad", sidoo kale loo yaqaan 6DoF. 

Quest waxa uu ku dhaqaajiyaa dareemaha kamarada madaxa madaxa laftiisa, xaaladan oo kale waxa uu gelinayaa meelo istiraatiji ah qalabka. Sameecado kale ayaa laga yaabaa inay isticmaalaan kamarado badan si ay u hagaajiyaan saxnaanta. Afartan kamaradood waxay u oggolaanayaan Quest inay eegaan adduunka dhabta ah ee kugu xeeran oo ay go'aamiyaan waxa booskaagu ku yaal meel bannaan. 

Taasi waa ta u ogalaata Quest^(Quest) in uu ahaado mid iskiis u kooban oo la qaadi karo. Sidoo kale waa sifada u ogolaanaysa la socodka gacanta ee Oculus si ay suurtogal u noqoto meesha ugu horeysa.

Xakamaynta Oculus Touch Standard^{(Standard Oculus Touch Controllers)}

Si loo fahmo waxa ka dhigaya raadinta gacanta Oculus mid cajiib ah, waa inaan ku bilownaa kontaroolayaasha jireed ee aan caadiga ahayn ee la socda Quest Oculus^{(Oculus Quest)} . Mid kasta waxa si buuxda u dhaqaajinaya dareemaha gudaha iyo calamadaha raadraaca dhaqdhaqaaqa gaarka ah ee u sheega kamaradaha dushiisa ee Quest halka kontaroolayaashu ay qaraabo yihiin dhegaha-dhegaha.

Marka aad ku hayso kontaroolayaasha taabashada VR, waxaa lagula socdaa saxnaan aan qarsoodi ahayn. Isticmaalka badhamada xajinta iyo kicinta ee kontaroolaha, software VR wuxuu abuuri karaa waayo-aragnimo lagu qanci karo oo ah qabashada iyo wax-ka-beddelka alaabta. Tan waxaa loo isticmaalaa in si weyn saameyn ugu leh ciyaaraha sida Half-Life Alyx iyo Climb The^{(The Climb)} , halkaas oo alaabta la qabsado ee adduunka VR ay tahay qayb udub dhexaadka ciyaarta. 

Xakamaynta taabashada^{(Touch Controllers)} sidoo kale waxay bixiyaan jawaab celin haptic ah iyada oo ay ugu mahadcelinayaan aaladaha loo yaqaan " actuators toosan ", kuwaas oo abuuri kara dareen jireed oo ku dhaca walxaha, gariirka iyo dareenka taabashada kale. Suulka iyo badhamada sidoo kale waxay bixiyaan hab la yaqaan oo loogu wareego meel VR ah marka aadan jir ahaan u dhaqaaqi karin goobtaada dhabta ah.

Khasaaraha ugu weyn ee tan marka la barbar dhigo gacan-raadinta waa inaad leedahay qabsatooyin gacmaha ah. Waxaad ku samayn kartaa dhaqdhaqaaqyo qanjaruufo fudud gacmahaaga casriga ah, laakiin taasi waa inta ay le'eg tahay. Ma dareemayso xaddidaad weyn marka ciyaaraha lagu nashqadeeyo agagaarka koontaroolayaasha, laakiin dabagalka gacantu waxay furtaa fursado cusub oo VR ah.

Muxuu Qabtaa Oculus Gacan-Raadgelinta

Marka la socodka gacanta la furo, waxaad arki doontaa matalaad sax ah ee gacmahaaga dhabta ah gudaha VR adduunka. Dhaqdhaqaaq kasta oo farahaaga ama curcurkaagu wuxuu ka muuqan doonaa doppelgangers-ka-yaqaanka ah.

Dabagalka gacantu^{(Hand Tracking)} hadda maahan sifada Quest . Hadda waxa lagu dhex daray nidaamka qalliinka iyo codsiyo badan oo xisbiga koowaad ah^(Quest) . Faa'iidada ugu weyn ee ugu horreysa halkan waa in haddii aad si dhakhso ah u rabto inaad xidhato Questada^(Quest) oo aad daawato filim VR ama ka dhex baadho dukaanka app-ka, uma baahnid inaad dhex gasho dadaalka aad ku dhejinayso kontaroolayaasha taabashada. Adigoo isticmaalaya gacmahaaga oo keliya, waxaad geli kartaa nidaamka menus oo aad si fudud ugu dhex wareegi kartaa.

Hadda gacanta ku-raadinta waa sifada rasmiga ah ee Quest , soo-saarayaasha abka saddexaad waxay ku dari karaan barnaamijyadooda. Waxa horeba u jiray tiro abka ah oo si fiican uga faa’iidaysata astaanta daba-galka gacanta ee Oculus , laakiin waxaanu hubnaa in horumariyayaashu ay heli doonaan habab badan oo xiiso leh oo gacan-raadinta tooska ahi u beddeli karto khibradda VR

Sida Oculus Gacan-raadinta u shaqeyso

Natiijooyinka gacan-raadinta ayaa ah kuwo aad u cajiib ah, laakiin sidee ayay dhab ahaantii u shaqeysaa? Sida iska cad Oculus ma daabici doono faahfaahinta saxda ah ee xalkooda lahaanshaha, laakiin waxaan ognahay tignoolajiyada iyo mabaadi'da ku lug leh.

Marka hore, kamaradaha dusha sare ku yaal ayaa lama huraan u ah samaynta gacan-raadinta shaqada. Ma aha oo kaliya inay bixiyaan macluumaadka qoto dheer ee stereoscopic, laakiin sidoo kale xogta muuqaalka ah ee lagu farsameeyo aragtida mashiinka. Waa maxay aragtida mashiinka? Waa laan ka mid ah sirdoonka macmal^{(artificial intelligence)} , gaar ahaan goobta loo yaqaan barashada mashiinka. Waa tignoolajiyad la mid ah oo u oggolaanaysa app kamarada taleefankaaga inay si dhakhso leh u aqoonsato wejiyada sawirka.

Asal ahaan, software-ku waa inuu bartaa waxa ku jira xogta sawirka ay bixiso kamaradu waa gacan iyo waxa aan gacanta ahayn. Tan waxa ay u badan tahay in la sameeyay iyada oo tusinaysa software-ka kumanaan iyo kun oo gacmood meelo kala duwan ilaa ay si kalsooni leh u garan karto hab degdeg ah oo waxtar leh oo iyaga loogu sheego marka laga reebo wax kasta oo qolkaaga ku jira.

Marka software-ku uu abuuri karo qaab sax ah oo sax ah, oo wakhtiga dhabta ah ee gacmahaaga, horumarinta app-ku waxay u isticmaali karaan wax kasta oo ay ka fikiri karaan. Waxaad hadda si sax ah u maamuli kartaa walxaha VR!

Waayo-aragnimada gacanta lagu raad-raacay ee mudan in la tijaabiyo

Haddii aad leedahay Oculus Quest , waxaad isku dayi kartaa habka raadraaca gacanta ee Oculus adoon iibsan app gaar ah. ^(Oculus)Sida kor ku xusan, waxay ka shaqeysaa deegaanka Quest -ka ugu weyn iyo sidoo kale dhowr apps oo xisbiga koowaad ah. Markay timaaddo waayo-aragnimada xisbiga 3aad, waxaa jira dhowr mudan in la muujiyo.

Khadku^{(The Line)} waa $4.99 waayo-aragnimo sheeko ah oo sidoo kale u adeegta sidii tignoolajiyada ugu habboon ee dabagalka gacanta. Waxay ka sheekaynaysaa sheekada magaalada moodeelka ah ee ku shaqeysa saacada iyo wadooyinka. 

Halyeygeena Pedro wuxuu jecel yahay Rosa , laakiin kama baxsan karo qaddarkiisa. Ilaa ay wax cusub dhacaan maalin. Waxaad la falgashaa qaabkooda cabirka aduunka adiga oo isticmaalaya gacantaada si aad u rogrogid burooyinkeeda, kabaalooyin u jiid oo aad ula qabsato wax kasta oo aad kari karto. Waa waayo-aragnimo toosan, oo gaaban, laakiin waxay muujin kartaa raad-raaca gacan-ku-taagga hab aad madadaalo leh ilaa 15 daqiiqo gudahood.

How Oculus Quest Hand Tracking Technology Works

The Oculus Quest (both the original and second model) have an interesting history of features being added long after the hardware is out in the wild. The most famous of these is Oculus Link, which effectively turns the Quest into an Oculus Rift. This feature was so successful that Oculus decided to discontinue all their headsets but the Quest. 

Hand tracking hasn’t made quite the splash Oculus Link did, but it’s still an amazing feature with lots of potential. With hand-tracking you don’t need controllers at all. Your own hands are digitized into the VR world! 

If you have a Quest or are thinking of buying one, it’s worth knowing how hand tracking works and what it can bring to the VR experience.

How Quest Tracks the World

The Oculus Quest uses an innovative approach towards motion tracking that’s commonly referred to as “inside-out” tracking, which is very different from how motion tracking worked in the past. 

When the first next-generation headsets were released in the mid-2010s, they made use of one or more external tracking cameras. Special motion tracking lights on the headset told the camera exactly where the headset was in relation to it. With some clever math, that data could then be converted to very accurate motion tracking in 3D space. This is how premium VR headsets offer “six degrees of freedom”, also known as 6DoF. 

Quest moves the camera sensor onto the headset itself, in this case placing them in strategic spots on the device. Other headsets may use even more cameras to improve accuracy. These four cameras let the Quest look at the real world around you and determine what your position is within that space. 

That’s what allows the Quest to be self-contained and portable. It’s also the feature that allows for hand-tracking with the Oculus to be possible in the first place..

The Standard Oculus Touch Controllers

To understand what makes Oculus hand tracking so impressive, we have to start with the rather mundane physical controllers that come with the Oculus Quest. Each one is fully motion-tracked by internal sensors and special motion tracking markers that tell the Quest’s onboard cameras where the controllers are relative to the headset.

When you’re holding the touch controllers in VR, they’re tracked with uncanny accuracy. Using the grip and trigger buttons on the controller, VR software can create a convincing experience of grabbing and manipulating items. This is used to great effect in games such as Half-Life Alyx and The Climb, where gripping items in the VR world is a central part of gameplay. 

The Touch Controllers also offer haptic feedback thanks to devices called “linear actuators”, which can create physical feelings of bumping into things, vibration and other touch sensations. Thumbsticks and buttons also offer a familiar way to move around a VR space when you can’t physically move about in your real space.

The main disadvantage of this compared to hand-tracking is that you have hooks for hands. You can perform simple pinching movements with your virtual hands, but that’s the extent of it. It doesn’t feel like a major limitation when games are designed around the controllers, but hand tracking opens a spectrum of new possibilities in VR.

What Oculus Hand-Tracking Does

When hand tracking is enabled, you’ll see an accurate representation of your real hands within the VR world. Each movement of your fingers or wrist will be reflected in their virtual doppelgangers.

Hand Tracking is no longer a beta feature of Quest. It’s now integrated into the operating system and many first party Quest applications. The first major benefit here is that if you just quickly want to put on your Quest and watch a movie in VR or browse around the app store, you don’t have to go through the effort of strapping on the touch controllers. Using just your hands, you can access system menus and navigate around with ease.

Now that hand-tracking is an official feature of Quest, third-party app developers can add it to their apps. There are already a number of apps that make excellent use of the Oculus hand-tracking feature, but we’re sure developers will find many more exciting ways in which direct hand-tracking can transform the VR experience

How Oculus Hand-tracking Works

The results of hand-tracking are pretty amazing, but how does it actually work? Obviously Oculus isn’t going to publish the exact details of their proprietary solution, but we do know the technologies and principles involved.

First, the on-board cameras are essential to making hand-tracking work. Not only do they provide stereoscopic depth information, but also visual data for processing by machine vision. What’s machine vision? It’s a branch of artificial intelligence, specifically a field known as machine learning. It’s the same technology that lets your phone’s camera app quickly identify faces in a photo.

Essentially, the software has to learn what in the image data provided by the camera is a hand and what isn’t a hand. This was probably done by showing the software thousands and thousands of hands in different environments until it could reliably figure out a fast and effective way of telling them apart from everything else in your room.

Once the software can create accurate, real-time virtual models of your hands, app developers can use them for anything they can think of. You can now precisely manipulate objects in VR!

Hand-tracked Experiences Worth Trying

If you own an Oculus Quest you can try out the Oculus hand-tracking feature without having to buy any particular app. As mentioned above, it works in the main Quest environment as well as a few first-party apps. When it comes to 3rd-party experiences, there are a few worth highlighting.

The Line is a $4.99 narrative experience that also serves as a perfect tech-demo for hand tracking. It tells the tale of a scale model town that runs on clockwork and tracks. 

Our hero Pedro is in love with Rosa, but he can’t escape his fate. Until something new happens one day. You interact with their scale model world by using your hand to turn knobs, pull levers and fiddle with everything that you can. It’s a linear, short experience, but can show off hand-tracking in a very entertaining way in about 15 minutes.

Waltz of the Wizard ($9.99) is another excellent showcase of the technology. You can use your hands to cast spells and interact with just about everything in the VR world around you. If you’ve ever wanted to live out the fantasy of being a wizard who can shoot bolts of lighting from their hands, this is the game for you!
